I'm not in a rush to defend Chomsky generally, I might not have been able to listen to it properly because of my setting, but it just seems like he's stating some facts, and in relation to those facts he can be read differently
he says

right libertarians try to prevent private power from being restrained

right libertarians hope that the state won't be captured by the people and used against private power

because in "this world", this context, the state does have the potential power to do that

this is not so much an endorsement the state but an explanation of the action/thought of right wing defenders of private power
